Slots and openings on the cabinet top, back, and bottom are provided for ventilation. To ensure safe and reliable operation of this unit, and to protect it from overheating, do not block or cover these openings. [. . . ] If it is, you will only be able to adjust the audio for whichever channel is selected on the Main Video Source bus. Set the Audio Bus Selectors (see below) to both "Video" and "Master" (LED is lit), and push the Master fader to 9 or Max, and set the other faders to 6 or Unity. Then, select a channel (A, B, C, D) and while listening to the audio and watching the Audio Level Meters (see below), set the level with the rotary pot so that the sound is consistently at between +3 dB (green LED) and +6 dB (yellow LED) and jusT-Barely peaks occasionally to +9 dB (red LED). The idea is to avoid any audible distortion (clipping), caused by making the signal level too high at this stage. The audio (A, B, C, D) selected at this bus is fed to the main Audio Bus at the Video channel below. Above three selectors on the left are the inputs (Aux-1, Aux-2, Video), which determine what signals are present at the Main Output. "Master" button controls the Main Audio Output, if the Master button is not selected, there will be no audio heard at the output. 33 These faders correspond to the selector buttons above and control the relative volume of each input in the master output as well as the master output level. They are called faders because they are used to decrease (rather than increase) the signal levels to make a balanced and pleasing mix. When they are set at Unity, at 6, they pass the audio signal through at the same level it was at when it entered this bus. This is why level setting at the Input Bus is so important. These meters show the audio signal level at the Main output. The strength of any audio signal that is routed to the output will be displayed here. As mentioned above, these meters play a vital part in correctly setting the audio levels to avoid clipping or other distortion. You'll notice that the LEDs are green up through the +0 dB level, turn yellow at +4 dB, and turn red at +10 dB. As you set the audio level for each input, make sure that the signal peaks to +8 dB or very occasionally to +9 dB. Every time the signal goes to +12 dB, it will be distorted. Use the Headphone section to accurately monitor any of the sources (Microphones, Aux-2, Aux-1 (MSC), "Video" (VCR) or "Master" output. Repeated presses of the Headphone button cycle through the monitoring choices. In many cases, headphones may be a more useful and accurate choice than speakers for audio monitoring. For example, in a noisy club or at a concert, you won't be able to hear any additional sound coming through speakers. Headphones will also more accurately reproduce the sound you wish to monitor at a lower cost than speakers. 34 Voice sync *. VOICE SYNC" function is available to correct the Audio input from the selected "Video" (A, B, C or D) channels or MIC/AUX-2 terminals. When engaged, this control allows you to compensate for delays in the video as it travels through the various components, processors, and converters of the Switcher, so that the video maintains sync with the audio. This control is adjustable from +3 frames (audio advanced) to ­19 frames (audio delayed) to the main Audio bus at the "Video" channel and affect the video/audio sync at the Master Output. Adjust this control while watching the Master Video Output on a monitor and listening to the Main Audio Out. When you use MIC in the front panel or AUX2 in the back panel as one of your audio input source, you could also use audio delay function.
